A Comparative Study of the Arithmetical Achievement Made by Boys and Girls of the Seventh Grade of Ozona Junior High School, Ozona TexasCushing, J. B. 08 1900 (has links)
The primary purpose of the study was to determine, scientifically, if there is any significant difference between the ability of boys in the seventh grade and the ability of girls in the same grade to retain arithmetical ideas, facts, and processes. A second purpose was to investigate the causes of differences that were found to exist.

Verhoging van laerskoolleerlinge se vlak van bewustheid van die distributiewe eienskap in rekenkundeVermeulen, Cornelis Franz January 1995 (has links)
Thesis (DEd)--Stellenbosch University, 1995. / ENGLISH ABSTRACT: The rationale for this study essentially is the perceived and reported misconceptions in
algebra that exist within pupils in the Junior Secondary phase. These misconceptions are the
direct result of the incomplete mastery of algebra.
The purpose of this research is to attempt to contribute towards pupils' complete mastery of
algebra and the ensuing elimination of certain pupil misconceptions, by trying to increase
primary school pupils' level of awareness of the general number properties.
Primary school pupils who learn arithmetic in a problem based environment intuitively use
the general number properties to execute arithmetical calculations, while pupils in the
traditional teaching approach are taught standard algorithms which they must apply, often
without comprehension.
In the latter, the existence of the number properties is concealed. When these pupils officially
encounter the general number properties for the first time in standard 4 or 5, they are
probably not capable of integrating these new concepts into their existing knowledge
structure. This may lead to incomplete mastery and ensuing misconceptions, which can
become worse when pupils must apply exactly the same number properties in algebra to
execute algebraic manipulations.
The fact that primary school pupils in the problem based approach intuitively apply the
number properties, earlier led to the hypothesis that these pupils possess a higher level of
awareness of the number properties. However, research has indicated that these pupils
possess only a moderately higher level of awareness. This has led to this study during which
a specific attempt is made to take pupils' intuitive knowledge of the number properties,
which they spontaneously apply, as a point of departure, and to develop it to such an extent
that they become explicitly aware of the existence and nature of these fundamental concepts
in mathematics.
The technique how to link up with pupils' intuitive knowledge and to increase their level of
awareness of the number properties inside a problem based environment, was developed during the first two years of this study. At the end of this period, a suitable teaching strategy
was formulated. This strategy is essentially based on the following parameters: Group
discussion, the use of calculators, and creating a cognitive disequilibrium. During the third
year of this study this strategy was implemented at a number of schools. During this phase
research concentrated on the distributive property only. Judging by the results, it appears as
if a considerable increase in level of awareness has taken place within these pupils.
During this study a hierarchical model of levels of awareness was also formulated. This
model was used as a guide in the attempt to increase pupils' level of awareness of the
number properties. / AFRIKAANSE OPSOMMING: Die rasionaal vir hierdie studie is hoofsaaklik gelee in die waargenome en gerapporteerde
wanbegrippe in algebra wat by leerlinge in die Junior Sekondere fase bestaan. Hierdie
wanbegrippe is die direkte gevolg van die onvolledige beheersing van algebra.
Die doel van hierdie navorsing is om 'n hydrae te probeer lewer tot leerlinge se volledige
beheersing van algebra, en die gepaardgaande uitskakeling van bepaalde leerlingwanbegrippe,
deurdat gepoog word om laerskoolleerlinge se vlak van bewustheid van die algemene
bewerkingseienskappe te verhoog.
Laerskoolleerlinge wat probleemgebaseerde rekenkunde-onderrig ontvang, benut intu'itief die
algemene bewerkingseienskappe ten einde rekenkundige berekeninge uit te voer, terwyl aan
laerskoolleerlinge in die tradisionele onderrigbenadering standaardalgoritmes onderrig word
wat hulle dikwels sonder begrip moet toepas.
In laasgenoemde geval word die bestaan van die bewerkingseienskappe erg versluier.
Wanneer hierdie leerlinge in standerd 4 of 5 vir die eerste keer amptelik met die algemene
bewerkingseienskappe in aanraking kom, is hulle waarskynlik nie in staat om hierdie nuwe
begrippe met hul bestaande kennisstruktuur te integreer nie. Dit kan tot onvolledige
beheersing en gevolglike wanbegrippe lei, wat kan vererger wanneer leerlinge presies
dieselfde eienskappe in algebra moet benut ten einde algebra!ese manipulasies uit te voer.
Die feit dat laerskoolleerlinge in die probleemgebaseerde benadering intu'itief die
bewerkingseienskappe toepas, het tevore reeds tot die hipotese dat hierdie leerlinge oor 'n
hoer vlak van bewustheid van die bewerkingseienskappe beskik, aanleiding gegee. Navorsing
het egter aangetoon dat daar slegs 'n matige hoer vlak van bewustheid by hulle bestaan. Dit
het tot hierdie studie aanleiding gegee waartydens spesifiek gepoog word om leerlinge se
intuitiewe kennis van die bewerkingseienskappe wat hulle spontaan aanwend ten einde
rekenkundige bewerkings uit te voer, as vertrekpunt te neem, en te ontwikkel sodat hulle
eksplisiet bewus sal raak van die bestaan en wese van hierdie grondliggende waarhede in
wiskunde.
Die tegniek hoe om by laerskoolleerlinge se intui'tiewe kennis aan te sluit en hul vlak van
bewustheid van die bewerkingseienskappe binne 'n probleemgebaseerde omgewing te
verhoog, is gedurende die eerste twee jaar van hierdie studie ontwikkel. Aan die einde van
hierdie periode is 'n toepaslike onderrigstrategie geformuleer. Hierdie strategie steun sterk
op die volgende parameters: Groepsbespreking , die benutting van sakrekenaars, en die skep
van 'n kognitiewe disekwilibrium. Gedurende die derde jaar van hierdie studie is hierdie
onderrigstrategie in verskeie skole toegepas. Daar is gedurende hierdie fase slegs op die
distributiewe eienskap gekonsentreer. Volgens die resultate wil dit voorkom asof daar 'n
aansienlike verhoging in die betrokke leerlinge se vlak van bewustheid van die distributiewe
eienskap plaasgevind het.
Gedurende hierdie studie is ook 'n hierargiese model van vlakke van bewustheid geformuleer
aan die hand waarvan die poging aangewend is om leerlinge se vlak van bewustheid van
bewerkingseienskappe te verhoog.

Entrants to training college : an investigation into the ability in, aptitude for and attitude towards arithmetic and mathematics, displayed by entrants to training colleges for White persons in the Cape ProvinceVenter, Ian Andri January 1973 (has links)
In many cases topics for research are presented to a student in capsulated, clearly defined terms, either as the result of his own experience or as a request by some institution. In other cases the topic takes shape but gradually, very often as the result of a student slowly becoming aware of a field of research through repeated observation of related factors. In some cases the aim of research is to determine whether there is a relationship between various factors; or disprove such in others the main aim may be to prove relationship in unequivocal terms. A large body of research is, however, concerned mainly with the statement of a problem or the finding of facts. The work presented in the following pages can be regarded as falling in the last-mentioned category. A vague suspicion was gradually strengthened by observation and experience until it finally crystallised to form the basis of the research. Facts and figures were gathered and analysed and some conclusions drawn, conclusions that gave rise to more questions and problems than fall within the scope of this work. It was, in fact, found that this research raised more questions than were answered by it and served mainly to underline the magnitude of the problem rather than to offer a solution.

The Effects of Self-evaluation and Response Restriction on Letter and Number Reversal in Young Children.Strickland, Monica Kathleen 08 1900 (has links)
The purpose of this study was to evaluate the effects of a training package consisting of response restriction and the reinforcement of self-evaluation on letter reversal errors. Participants were 3 typically developing boys between the age of 5 and 7. The results indicated that the training package was successful in correcting reversals in the absence of a model during training and on application tests. These improvements maintained during subsequent follow-up sessions and generalized across trainers. Fading was not always necessary in correcting reversals, but was effective in correcting reversals that persisted during the overlay training procedures. The advantages to implementing a systematic intervention for reducing letter reversal errors in the classroom, as well as directions for future research, are discussed.
